Evaluation of the efficacy of endoscopic posterior nasal neurectomy with pharyngeal neurectomy of allergic rhinitis combined with chronic rhinosinusitis with nasal polyps / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the effect of posterior nasal neurectomy（PNN） with pharyngeal neurectomy （PN） on chronic sinusitis with nasal polyps （CRSwNP）complicated with perennial allergic rhinitis （PAR）. Methods:83 patients with perennial allergic rhinitis combined with chronic group-wide sinusitis with nasal polyps who attended our hospital from July 2020 to July 2021 were selected. All patients underwent conventional functional endoscopic sinusitis surgery（FESS）+ nasal polypectomy. Patients were divided according to whether they underwent PNN+PN. 38 cases in the experimental group underwent FESS combined with PNN+PN; 44 cases in the control group underwent conventional FESS alone. All patients underwent the VAS, RQLQ, and MLK before treatment, and at 6 months and 1 year after surgery. Meanwhile, other relevant data were collected and the preoperative and postoperative follow-up data were collected and analyzed to assess the differences between the two groups. Results:The total postoperative follow-up period was 1 year. The recurrence rate of nasal polyps at 1 year postoperatively and the nasal congestion VAS score at 6 months postoperatively were not statistically significant in the two groups（P>0.05）. However, the patients in the experimental group had statistically significantly lower effusion and sneezing VAS scores, MLK endoscopy scores and RQLQ scores at 6 months and 1 year postoperatively, and nasal congestion VAS scores at 1 year postoperatively compared to the control group（P<0.05）. Conclusion:For patients with perennial AR complicated with CRSwNP, the combination of the PNN+PN in FESS can significantly improve the short-term curative effect, and PNN+PN is a safe and effective surgical treatment.

Objective:To analyze and summarize the clinical efficacy and safety of lymphocyte apheresis combined with plasma exchange in the treatment of patients with hepatitis B virus-related liver failure at the ascending stage.Methods:A observational study was conducted. A total of 69 hepatitis B virus-related liver failure at the ascending stage patients who were hospitalized at Affiliated Guangzhou Eighth People's Hospital of Guangzhou Medical University from January 2016 to December 2020 were enrolled in this study. The patients were grouped according to their condition and wishes, including 38 patients treated with conservative medical treatment (control group) and 31 patients treated with lymphocyte apheresis combined with plasma exchange based on comprehensive medical treatment (study group). Clinical data were compared between the two groups 1-4 weeks after treatment, including dynamic changes of total bilirubin (TBil), international normalized ratio (INR), alanine aminotransferase (ALT), model for end-stage liver disease (MELD) score, and the rate of clinical improvement at 4 weeks after treatment. In addition, the adverse effects and dynamic changes of white blood cell count (WBC), lymphocyte count (LYM), platelet count (PLT), and hemoglobin (Hb) within 4 weeks after treatment were compared between the two groups.Results:Both groups showed significant improvement in clinical parameters after 1-4 weeks of initiation of therapy. The improvement of TBil, INR and MELD score at 1-4 weeks after treatment were significantly better in the treatment group than those in the control group [TBil (μmol/L): 248 (117, 335) vs. 398 (328, 464) at 1 week, 173 (116, 278) vs. 326 (184, 476) at 2 weeks, 107 (84, 235) vs. 355 (129, 467) at 3 weeks, 70 (61, 172) vs. 290 (82, 534) at 4 weeks; INR: 1.72±0.70 vs. 2.13±0.69 at 1 week, 1.67±0.61 vs. 2.28±1.35 at 2 weeks, 1.65±0.75 vs. 2.15±0.92 at 3 weeks, 1.61±0.93 vs. 2.19±1.17 at 4 weeks; MELD score: 18.35±5.32 vs. 23.38±4.56 at 1 week, 16.47±5.16 vs. 23.71±7.94 at 2 weeks, 16.30±5.75 vs. 22.64±6.99 at 3 weeks, 14.63±6.76 vs. 20.97±8.19 at 4 weeks], with significant differences (all P < 0.05). In addition, ALT levels at 1 week and 2 weeks after treatment in the study group were significantly lower than those in the control group [U/L: 128 (93, 206) vs. 240 (167, 436) at 1 week, 64 (42, 110) vs. 85 (69, 143) at 2 weeks, both P < 0.05]. The rate of clinical improvement at 4 weeks after treatment in the study group was 54.84% (17/31), which was significantly higher than that in the control group [28.95% (11/38)], with statistically significant difference ( P < 0.05). There was no significant difference in the rate of new infection between the study group and the control group [22.58% (7/31) vs. 34.21% (13/38), P > 0.05]. Additionally, expect that the PLT level at 1 week after treatment in the study group was significantly lower than that in the control group (×10 9/L: 101±42 vs. 128±59, P < 0.01), there was no significant difference in WBC, LYM or Hb at different time points after treatment between the two groups. Conclusion:Clinical efficacy of lymphocyte apheresis combined with plasma exchange based on comprehensive medical treatment in the treatment of patients with hepatitis B virus-related liver failure at the ascending stage is superior to conservative medical treatment alone, which can improve clinical improvement rate and recovery rate of liver function with high safety.

Efficacy and influencing factors of anlotinib in treatment of elderly patients with small cell lung cancer after second-line treatment failure / 国际肿瘤学杂志

Objective:To investigate the efficacy and influencing factors of anlotinib in treatment of elderly patients with small cell lung cancer after second-line treatment failure.Methods:A total of 56 elderly patients with small cell lung cancer who were diagnosed and treated in the Tumor Hospital Affiliated to Xinjiang Medical University from September 2018 to February 2020 were collected. All patients were treated with anlotinib capsule after failure of second-line chemotherapy, objective response rate (ORR), disease control rate (DCR) and progression-free survival (PFS) were calculated, and ORR, DCR and PFS of patients with different clinical characteristics were compared. Cox proportional hazards model was used to analyze the factors influencing PFS in elderly patients with small cell lung cancer, and adverse drug reactions were observed.Results:After 2 cycles of treatment, the ORR and DCR of 56 elderly patients with small cell lung cancer were 10.7% (6/56) and 53.6% (30/56) respectively. Among them, the ORR and DCR of patients without brain metastasis were 20.8% (5/24) and 75.0% (18/24), which were higher than 3.1% (1/32) and 37.5% (12/32) in patients with brain metastasis, with statistically significant differences ( χ2=4.496, P=0.034; χ2=7.754, P=0.005). The ORR and DCR of patients with Eastern Cooperative Oncology Group (ECOG) score of 0-1 were 21.7% (5/23) and 69.6% (16/23), which were higher than those of patients with ECOG score of 2-3 [3.0% (1/33), 42.4% (14/33)], with statistically significant differences ( χ2=4.959, P=0.026; χ2=4.014, P=0.045). ORR and DCR were not related to gender, age, clinical stage or smoking status (all P>0.05). The median PFS of 56 patients was 3.8 months. The median PFS of patients aged ≤70 years was 5.0 months, and that of patients aged >70 years was 3.4 months, with a statistically significant difference ( χ2=5.452, P=0.020). The median PFS of patients without brain metastasis was 5.1 months, and that of patients with brain metastasis was 3.2 months, with a statistically significant difference ( χ2=8.895, P=0.003). The median PFS of patients with ECOG score of 0-1 was 5.0 months, and that of patients with ECOG score of 2-3 was 2.9 months, with a statistically significant difference ( χ2=5.923, P=0.015). The median PFS of patients with limited stage was 5.0 months, and that of patients with extensive stage was 3.1 months, with a statistically significant difference ( χ2=5.141, P=0.023). Cox multivariate analysis showed that ECOG score ( HR=2.522, 95% CI: 1.378-4.615, P=0.003) and brain metastasis or not ( HR=0.323, 95% CI: 0.168-0.622, P=0.001) were independent prognostic factors of PFS. During the treatment of anlotinib, the main adverse reactions were grade Ⅰ-Ⅱ, grade Ⅲ-Ⅳ adverse reactions were mainly hypertension and hand-foot syndrome, which improved after drug reduction and symptomatic treatment, and could be tolerated later. The incidence of drug reduction was 3.6% (2/56), and there were no patients with drug interruption or termination of treatment. Conclusion:Anlotinib has good short-term efficacy and survival benefits in the treatment of elderly patients with small cell lung cancer after second-line treatment failure. It has good therapeutic effect for patients with low ECOG score and without brain metastasis, and has tolerable adverse reactions and high safety.

Objective:To explore the precision treatment effect of multidrug-resistant pulmonary tuberculosis (MDR-PTB) based on the proportion method for drug susceptibility test, and to provide a scientific basis for formulating MDR-PTB treatment plan.Methods:One hundred and eighty patients with MDR-PTB treated in Shenzhen Center for Chronic Disease Control from January 5, 2016 to April 30, 2018 were enrolled. The initial treatment plan after diagnosis was six months of amikacin (AM), pyrazinamide (Z), levofloxacin (LFX), ethambutol (E), prothionamide (PTO) and 18 months of Z, LFX, E, PTO. According to whether proportion method for drug susceptibility test for 10 commonly used drugs was implemented, patients were divided into precision treatment group and empirical treatment group. In the precision treatment group, the treatment plans were adjusted according to the results of the drug susceptibility test. The treatment plans and disease outcomes of the two groups of patients were retrospectively analyzed. Chi-square test was used for statistical analysis.Results:Among the 180 patients, there were 113 patients in the precision treatment group and 67 patients in the empirical treatment group. The drug resistance rates of the precision treatment group from low to high were: capromycin (CM) (0, 0/113), AM (2.65%, 3/113) and kanamycin (KM) (2.65%, 3/113), para-aminosalicylic acid (PAS) (7.96%, 9/113), PTO (11.50%, 13/113), ofloxacin (OFX)(38.05%, 43/113), E (39.82%, 45/113), and streptomycin(S) (76.99%, 87/113). In the precision treatment group, the drugs were adjusted for 104 person-times according to the proportion method for drug susceptibility test during the treatment, from low to high: AM (3 person-times), PTO (13 person-times), LFX (43 person-times) and E (45 person-times). The treatment success rate of the precision treatment group was 78.8%(89/113), which was higher than that of the experience treatment group (52.2%(35/67)), the difference was statistically significant ( χ2=13.805, P=0.000 2). In the precision treatment group and empirical treatment group, there were no statistically significant differences of alanine aminotransferase elevated (32.3%(31/96) vs 34.0%(18/53)), serum creatinine elevated (4.2%(4/96) vs 5.7%(3/53)), and white blood cell count decreased (24.0%(23/96) vs 22.6%(12/53)) (all P>0.05). Conclusion:The traditional treatment plan based on the proportion method for drug susceptibility test has a high success rate in the treatment of MDR-PTB, which is still a worthy choice.

Objective To explore the clinical curative effect of interventional treatment of fibroids, evaluate its clinical application effect and provide a reference for future clinical treatment. Methods This study retrospectively analyzed the clinical data of 29 fibroid cases who admitted in our hospital from March 2016 to March 2019. All patients were performed X-ray guided uterine artery embolization (UAE). The study observed and recorded the volume of uterine and fibroid, menstruation, hormone levels, the post-operative complications etc. before and after the treatment. Results Patients were reexamined once every three months after the treatment, three times in a row. It was found that the patients’ postoperative uterine volume and fibroid volume were significantly smaller than preoperative volume (P < 0.05), and the difference was statistically significant. The postoperative menstrual cycle, menstruation, menstruation time were significantly improved (P < 0.05), and the difference was statistically significant. The postoperative LH, E2, FSH levels had no significant change (P > 0.05), and the difference was not statistically significant. There were two abdominal pain cases, one hematoma case and one vomite case during the postoperative observation period. These symptoms disappeared after the symptomatic treatment, and no serious symptoms such as high fever and pelvic infection occurred. Conclusion Interventional therapy of fibroids can effectively reduce the size of fibroids, significantly improve the quality of life of patients, with small damage, rapid recovery, preservation of the uterus and other advantages, which is worthy of further clinical application and promotion.

Avaliação econômica do uso de ômega-3 na redução dos fatores de risco cardiovascular: análise de custo-efetividade / Economic evaluation of omega-3 use in cardiovascular risk reduction factors: cost-effectiveness analysis

INTRODUÇÃO: As doenças cardiovasculares (DCV) aparecem em primeiro lugar entre as principais causas de mortalidade no mundo, representando 46,2% do total de mortes, número muito próximo aos encontrados no Brasil, impactando os gastos com saúde. A prevenção baseia-se em estilo de vida saudável, contudo, uma vez instaladas, é consenso o tratamento medicamentoso com estatinas. Alguns tratamentos alternativos vêm sendo estudados como o ômega-3 (w-3) na prevenção das DCV. Apesar das evidências clínicas favoráveis, não existem muitos estudos acerca da viabilidade econômica de tais tratamentos. OBJETIVO: Avaliar o custo-efetividade das intervenções com w-3 isolado ou associado às estatinas na redução dos fatores de risco cardiovascular sob a perspectiva do Sistema Único de Saúde (SUS). MATERIAL E MÉTODOS: Para avaliar a efetividade do w-3 isolado e combinado com estatina foram utilizados os dados secundários do ensaio clínico CARDIONUTRI no momento basal e após 8 semanas. A amostra foi composta por 186 indivíduos com idade entre 30 e 74 anos divididos entre aqueles que não tomavam medicação e os que tomavam estatinas. Aleatoriamente, uma parcela deles recebeu cápsulas de 1 g de w-3 (37% de ácido eicosapentaenoico e 23% de docosaexaenoico) ou cápsulas de placebo. A recomendação era de que todos deveriam tomar 3 cápsulas ao dia, totalizando 3g/dia (de w-3 ou placebo) durante 8 semanas. Ao final, obteve-se quatro grupos: a) w-3; b) placebo; c) w-3 + estatina; e d) estatina. Para a avaliação do impacto foi usado o método Diferenças em Diferenças com a adição de variáveis de controle: densidade calórica do consumo alimentar, Índice de Massa Corporal (IMC), prática de atividade física, idade, sexo, raça, hábito tabagista, escolaridade e grau de adesão. Os custos dos tratamentos foram estimados com base no custo médio ponderado pelas probabilidades das eventuais intercorrências relacionadas a efeitos adversos e de sucesso e fracasso por meio do método da árvore de decisão. Foi considerado para fins do cômputo dos custos o período de 2 meses de tratamento. RESULTADOS: Nos quatro grupos, a maioria eram mulheres, obesas e com escore de risco muito alto para DCV. Os grupos w-3 e placebo possuíam maior escolaridade e renda comparadas a aqueles que tomavam estatinas. Todas as variáveis de controle foram estatisticamente significantes em pelo menos um dos modelos, exceto raça. A suplementação com w-3 associada às estatinas mostrou efetividade sobre HDLPEQUENA, com diminuição de 2,211 mg/dL e custo-efetividade de R$ 109,31 por redução em mg/dl da lipoproteína em 2 meses de tratamento. CONCLUSÃO: O tratamento com 1,8g de óleo de peixe isolado ou associado às estatinas em intervenção primária não evidenciou efeitos significativos nas mudanças dos parâmetros lipídicos, exceto no caso da HDLPEQUENA com o tratamento associado, mostrando não ser custo-efetivo na redução dos fatores de risco cardiovascular em geral. Em virtude da existência de controvérsias acerca de seus potenciais efeitos, sugere-se que os ensaios clínicos utilizem métodos estatísticos mais robustos para avaliar o impacto líquido da suplementação

INTRODUCTION: Cardiovascular diseases (CVD) are among the leading causes of death worldwide, accounting for 46.2% of all cases, very close to those found in Brazil, impacting health expenses. Current prevention is based on a healthy lifestyle, and once a CVD diagnosis is made, the current consensus is drug treatments with statins. Some alternative treatments such as omega-3 (w-3) have been studied in the prevention of these diseases. However, despite favorable clinical evidence, there are not many studies of economic viability of this treatment. OBJECTIVE: To evaluate the cost-effectiveness of interventions with w-3 alone or associated with statins in reducing cardiovascular risk factors from the perspective of the Unified Health System (SUS). METHODS: To assess the effectiveness of w-3 alone and its combination with statin, the secondary data of the classic lipid profile and lipoprotein size of the CARDIONUTRI clinical trial were used at baseline and after 8 weeks. The sample consisted of 186 subjects aged 30 to 74 years randomly received capsules containing 3g of w-3 per day (37% of eicosapentaenoic acid and 23% of docosahexaenoic acid) or 3g of mineral oil (placebo). Capsules were randomly assigned to individuals who were not taking medication or were already taking statins, separated into four groups: a) w-3; b) placebo; c) w-3 associated with statins; d) statins. Data analysis was conducted using the Difference in Differences statistical method with the addition of control variables: caloric density of food consumption, Body Mass Index (BMI), physical activity practice, age, sex, race, smoking, educational level and adherence to the treatment. The treatment costs were estimated based on the weighted average cost by the probabilities of the eventual intercurrences related to adverse effects and of success and failure by means of the decision tree method elapsed in 2 months of treatment. RESULTS: In all four groups, the majority were women, obese and with a very high-risk score for CVD. W-3 and placebo groups had higher educational level and income compared to those who were already taking statins. All control variables were statistically significant in at least one of the models except race. W-3 supplementation showed efficacy on HDLSMALL among those who consumed w-3 + statins with a reduction of 2,211 mg /dL and cost-effectiveness R$ 109.31 per mg/dL for 2 months of treatment. CONCLUSION: The treatment with 1.8g of fish oil isolated or associated with statins in primary intervention did not show significant effects on changes in lipid parameters except HDLSMALL of interventions associated with statins. Therefore it was not cost-effective in reducing cardiovascular risk factors. Due to the existence of controversies about its potential effects, it is suggested that clinical trials use more robust statistical methods to assess the net impact of supplementation

Efficacy analysis of Altemeier and Delorme procedures for the rectal prolapse / 中华胃肠外科杂志

Objective@#To evaluate the quality of life after Altemeier and Delorme procedures for rectal prolapse patients.@*Methods@#A retrospective cohort study was performed. Clinical data of patients with full-thickness rectal prolapse undergoing surgical treatment in the Sixth Affiliated Hospital, Sun Yat-sen University from February 2013 to January 2018 were retrospectively analyzed. Patients who had no preoperative imaging data, who suffered from internal rectal intussusception, or who did not undergo Altemeier and Delorme operations were excluded. Sixty-seven patients were enrolled, including 32 males with median age of 20.5 (13, 34) years and 35 females with median age of 65.0 (50, 77) years. According to different procedures, patients were divided into the Altemeier group (48 cases) and the Delorme group (19 cases), who received standard Altemeier and Delorme operations respectively. The maximal prolapse length of preoperative squat position, the Longo constipation score, Wexner incontinence score, EQ-5D-5L score, postoperative complications and recurrence rate were analyzed and compared between two groups.@*Results@#The maximal prolapse length of preoperative squat position in Altemeier group and Delorme group was (7.3±3.3) cm and (4.9±2.1) cm respectively with significant difference (t=2.907, P=0.005). The operations in both groups were successfully completed. The operation time and postoperative hospital stay of Altemeier group were longer than those of Delorme group [(112.3±47.0) minutes vs. (80.7±35.4) minutes, t=2.637, P=0.010; (11.3±5.0) days vs. (8.6±3.0) days, t=2.177, P=0.033]. The median follow-up period was 26 (13, 45) months. In the last follow-up, compared to pre-operation, the Longo constipation score [9.0 (6.0, 14.0) vs 4.0 (1.0, 6.5), Z=-4.989, P<0.001], Wexner incontinence score [0 (0, 5.5) vs. 0 (0, 2.0), Z=-3.325, P<0.001] and EQ-5D-5L score [45.0 (40.0, 57.5) vs. 80.0 (70.0, 87.5), Z=-5.587, P<0.001] were all improved obviously in the Altemeier group, meanwhile Longo constipation score [6.0 (5.0, 14.0) vs. 3.0 (1.0, 7.0), Z=-2.186, P=0.029], Wexner incontinence score [0 (0, 12.0) vs. 0 (0, 4.0), Z=-2.325, P=0.020] and EQ-5D-5L score [50.0 (35.0, 60.0) vs. 75.0 (65.0, 90.0), Z=-3.360, P=0.001] in the Delorme group were all improved obviously as well. The postoperative morbidity of complication between the two groups was not significantly different [10/48 (20.8%) vs. 4/19 (21.1%), χ2=0.049, P=0.826]. Sixteen patients (28.0%) relapsed after operation, including 10 patients in the Altemeier group and 6 patients in the Delorme group, without statistically significant difference (P=0.134).@*Conclusions@#Both the Altemeier and Delorme procedures are effective treatments for rectal prolapse, which can improve the postoperative quality of life. Delorme procedure has the advantages of shorter operation time and faster postoperative recovery in patients with mild prolapse.

Clinical application of apatinib in the treatment of advanced bone and soft tissue sar-coma / 中国肿瘤临床

To observe the efficacy and safety of apatinib in the treatment of advanced bone and soft tissue sarcoma, and to analyze the possible related factors affecting the progression-free survival (PFS) of patients. Methods: Twenty-one patients with ad-vanced bone and soft tissue sarcoma admitted to the Department of Orthopaedics, Yunnan Cancer Hospital from June 2017 to Sep-tember 2018, were treated with apatinib tablets. The main efficacy index was progression free survival (PFS), and the secondary effica-cy index was overall survival (OS). Clinical efficacy was evaluated according to response evaluation criteria in solid tumors (RECIST) 1.1, and overall response rate (ORR), disease control rate (DCR), and safety were olserved according to the National Cancer Institute (NCI) 4.0 standard. Results: All of the 21 patients were followed up. At the last follow-up time point, March 31st, 2019, there were no CR, 2 patients (9.5%) with PR, 7 patients with SD (33.3%), and 12 patients with PD (57.1%). The ORR was 9.5%, the DCR was 42.8%, the medi-an PFS was 8 months, and the median OS was 14 months. The patient's gender, age, ECOG score, tissue source, surgery, or chemother-apy had no statistically significant effect on PFS (P>0.05). Only the history of radiotherapy before taking apatinib was a factor for pa-tients with PFS. The effect was statistically significant (P<0.05), and patients with a history of radiotherapy had a lower PFS than pa-tients without a history of radiotherapy. The adverse reactions of gradeⅢand above had hand-foot syndrome (14.3%), pneumotho-rax (14.3%) and anemia (4.8%). Conclusions: Apatinib has a certain effect for advanced bone and soft tissue sarcoma. The adverse re-actions are generally predictable, controllable and reversible. Apatinib can be a choice for patients with advanced bone and soft tissue sarcoma with good treatment adherence and no other treatment options.

All patients were given symptomatic supportive treatments such as potassium supplementation, catharsis, vital organ protections, neurotrophic drugs, and circulation support. The mild poisoning patients were given PB with an oral dose of 250 mg·kg-1·d-1, while moderate-severe poisoning patients were given PB combined HP continued 2-4 hours each time. The PB dose or frequency of HP application was adjusted according to the monitoring results of blood and urine thallium. Data of gender, age, pain grading (numeric rating scale NRS), clinical manifestations, blood and urine thallium before and after treatment, length of hospitalization and prognosis were collected.@*Results@#Of the 47 patients, patients with incomplete blood and urine test results, and used non-single HP treatment such as plasmapheresis and hemodialysis for treatment were excluded, and a total of 29 patients were enrolled in the analysis. ①Among 29 patients, there were 20 males and 9 females, median age of 40.0 (34.0, 49.0) years old; the main clinical manifestations were nervous system and alopecia, some patients had digestive system symptoms. There were 13 patients (44.8%) in the mild poisoning group with painless (grade 0) or mild pain (grade 1-3) with mild clinical symptoms, the length of hospitalization was 17.0 (14.2, 21.5) days. There were 16 patients (55.2%) in the moderate-severe poisoning group with moderate pain (grade 4-6) or severe pain (grade 7-10) with severe clinical symptoms, the length of hospitalization was 24.0 (18.0, 29.0) days. ② After treatment, the thallium concentrations in blood and urine in the mild poisoning group were significantly lower than those before treatment [μg/L: blood thallium was 0.80 (0, 8.83) vs. 60.00 (40.00, 120.00), urine thallium was 11.30 (0, 70.10) vs. 370.00 (168.30, 610.00), both P < 0.01], the thallium concentrations in blood and urine in the moderate-severe poisoning group were also significantly lower than those before treatment [μg/L: blood thallium was 6.95 (0, 50.50) vs. 614.50 (245.00, 922.00), urinary thallium was 20.70 (1.95, 283.00) vs. 5 434.00 (4 077.20, 10 273.00), both P < 0.01]. None of the 29 patients died, and their clinical symptoms were improved significantly. All the 27 patients had good prognosis without sequela in half a year follow-up, and 2 patients with severe acute thallium poisoning suffered from nervous system injury.@*Conclusion@#In the acute thallium poisoning patients, on the basis of general treatment, additional PB in mild poisoning group and PB combined with HP in moderate-severe poisoning group can obtain satisfactory curative effects.

Traditional Chinese medicine target identification based on"Target Fishing"strategy / 中国药理学与毒理学杂志

OBJECTIVE Our group mainly focuses on the target identification and pharmacological mechanism study of TCM.We deeply identified the direct targets of the active ingredients in TCM using molecule probe-'Target Fishing' technology in chemical biology, and explored the related signaling pathways to explain the traditional efficiency of TCM. METHODS We synthesized biotin-tagged mole-cule probe by connecting biotin tag to TCM active molecule using PGE as a linker. Then, the biotin-tagged molecule probe was bound to the surface of solid beads by strong biotin-avidin interaction. Thus, the molecule probe-bound beads were mixed with cell lysates to capture the potential targets and identified by MS.RESULTS Our study found that SA which was an anti-inflammatory compound-could selectively bind to IMPDH2 in microglial cells,and SA showed weaker anti-inflammatory effect on IMPDH2-knock down microglial cells,suggesting IMPDH2 as a key anti-inflammatory target for SA.Ad-ditionally,handelin was a key anti-inflammatory compound.We identified the target protein of handelin as Hsp70 from microglial cells using target pull-down technology. Moreover, handelin showed weaker anti-inflammatory effect on Hsp70-knock down microglial cells,revealing that Hsp70 was the direct anti-inflammatory target of handelin. CONCLUSION Our study provided methodology references for TCM target identification in the future, and also showed a new insight for exploring the pharmacological mechanism of TCM active ingredients.More importantly,we can perform scientific annotation for TCM efficiency by clarifying the biological functions of each target protein,showing important significance on modernization and internationalization of TCM.

Establishment of Scoring System for Risk Factors of Invasive Fungal Infection in Patients with Hematologic Diseases / 中国药房

OBJECTIVE:To establish a risk scoring system for identifying invasive fungal infection(IFI)patients with hematologic diseases. METHODS:Risk factors were investigated among 200 patients diagnosed with IFI and 200 control patients at the same time from Jan. 2008 to Dec. 2015. The single factor analysis and Logistic multivariate regression analysis were conducted for potential risk factors to screen and assign risk factors of IFI. The risk scoring system of IFI was established,the performance of scoring system was evaluated by receiver operating characteristic(ROC)curve. Using the scoring system,103 patients of validation group were scored during Jan. to Jun. in 2016.The incidence of IFI in each group was compared. 18 high-risk patients were intervened by the scoring system. RESULTS:Community acquired infection,the reduction of neutrophils,fungal infection history,corticosteroids and broad-spectrum antibiotics(Enzyme inhibitors,glycopeptides,quinolones,aminoglycosides and carbapenems)were risk factors of IFI(P<0.001),and the score of them were 17,10,39,14,14 according to the regression coefficients. IFI risk scoring system was divided into low,medium and high risk(scoring 0-30,31-40,≥41),AUC of ROC curve was 0.916. The incidence of IFI in low-risk,medium-risk and high risk groups were 3.0%,10.7% and 62.5%,high-risk group was significantly higher than low and medium-risk groups(P<0.05).The incidence of IFI was 16.7% in intervention group, there was statistical significance compared to high-risk group of validation group(P<0.05). CONCLUSIONS:This scoring system shows good ability to distinguish risk stratification. It can help clinicians identifying IFI high-risk groups and timely guiding timely intervention for patients.

@#Objective    To evaluate the clinical efficacy of fistula repair by stapler technique in patients with cervical tracheoesophageal fistula. Methods    Retrospective analysis of 8 patients with cervical tracheoesophageal fistula who accepted operative treatment in the Department of Thoracic Surgery, Lanzhou University Second Hospital from October 2014 to October 2016 was conducted. There were 5 males and 3 females at a mean age of 46.4±13.9 years ranging from 23 to 67 years. The fistula was induced by tracheal intubation in 4 patients, by esophageal foreign bodies in 2, by tracheal stent in 1 and by esophageal diverticulum in 1. The fistula was closed by stapler technique. The surgical effects were evaluated through Karnofsky performance score (KPS), image assessment, patient satisfaction score and assessment of improvement in feeding-induced bucking. Results    The operations were performed successfully with time of 117.5±6.6 min and intraoperative blood loss of 60.0±7.0 ml. After the operations, the patients did not suffer incision bleeding and infection, hoarseness, dyspnea, drinking-induced bucking, fistula relapse, tracheoesophageal stenosis or any other complications, and no death occurred during the perioperative period. The chest X-ray test was performed 1 week later showed that the pulmonary infection disappeared, and only 1 patient suffered from esophageal stenosis 1 year later. The postoperative KPS score was 90.0±7.0 points, which significantly improved in contrast to preoperation (P<0.01).   Postoperative pulmonary infection area reduced significantly (P<0.05), tracheoesophageal fistula disappeared, postoperative patients satisfaction rate was 90%, and assessment of feeding-induced bucking was excellent. Conclusion    Using stapler technique to repair cervical tracheoesophageal fistula is safe, easy and useful, with less operation time and postoperative complications.
